摘　　要：随着城市轨道交通的快速发展,地铁列车运行产生的振动对邻近建筑产生的不利影响得到了广泛关注。文章以拟建的济南轨道交通M1线(6号线)工程为例,选取大明湖东站附近的某办公楼为研究对象,建立了有限元模型,系统地研究列车开行情况、建筑物与地铁隧道间距等因素对结构振动响应的影响。结果表明:地铁列车开行时,结构3个方向的振动均属于低频振动,结构的振动速度没有超限;相比于单向列车开行,双向列车对开时,垂直和竖直隧道方向结构的振动速度均有所增大,而平行隧道方向的振动速度则有所降低;基于分析数据,建议两条隧道中心线与建筑物净距保持>4.5 m;从安全角度出发,在设计阶段可以在隧道内或土体中采用适当的减振、隔振措施;数值分析结果可以较好地体现地铁运行产生的振动过程。With the rapid development of urban rail transit,the adverse effect of vibration caused by subway train operation on adjacent buildings have garnered significant attention.In this paper,Jinan rail transit line M1(Line 6)was selected as a case study,and one office building near Daming Lake East Station was selected as the research object.The finite element models were established to systematically analyze the influence of factors such as the operation of subway train,and the distance between buildings and subway tunnels on structural vibration response.The results indicate that when the operation subway trains,the vibration in all three directions belongs of the structure are characterized as low frequency,and the vibration velocity does not exceed the limit value.When the two-way trains operations occur,the vibration velocity of the structure in the vertical tunnel direction and the vertical direction increases,whereas it decreases in the vibration velocity in the parallel tunnel direction.Based on the analysis data,it is recommended that the distance between the centerline of two tunnels and the building should be maintained above 4.5 m.In the view of safety point,appropriate vibration reduction and isolation measures can be adopted in the tunnel or soil during the design phase.The numerical analysis results can better reflect the vibration process generated by subway operation.
